[Advances in imaging diagnosis of mixed-type liver cancer]

Mixed-type liver cancer is a rare kind of primary malignant liver tumor with risk factors similar to those of hepatocellular carcinoma and intrahepatic cholangiocarcinoma, although treatment methods and prognosis differ. An early imaging diagnosis is helpful in adopting appropriate treatment strategies for mixed-type liver cancer. Since mixed-type liver cancer contains different proportions of hepatocellular carcinoma and cholangiocarcinoma in the same lesion, imaging manifestations may vary. This paper reviews the recent literature reports, imaging characteristics, and the latest imaging diagnostic techniques in relation to the imaging diagnosis of mixed-type liver cancer.
